How to convert two arrays into single array?-CodePudding

I have to convert two arrays into a single array base on given below condition. a= ["dry chapati", "dry chapati", "dry chapati"] b = ["chapati", "less fat", "no oil"];

I want to convert a and b to as below

c = ["dry chapati" : "chapati", "less fat", "no oil"]

I am trying it as below but not getting desired result as c

let recipe = ["dry chapati", "dry chapati", "dry chapati"];
let tags = ["chapati", "less fat", "no oil"];

let r = [];
for(let i=1; i<recipe.length; i  ){
    if(recipe[i] == recipe[i 1]){
        recipe[i] = tags
        // console.log(recipe);
    }
}

Please help to find a solution.

let recipe = ["dry chapati", "dry chapati", "dry chapati"];
let tags = ["chapati", "less fat", "no oil"]; 

let array3 = [...new Set(recipe.concat(tags) )];
console.log(array3);

let arr1 = ["dry chapati", "dry chapati", "dry chapati"];
let arr2 = ["chapati", "less fat", "no oil"];


const merge = (arr1, arr2) => {
  const res= [arr1[1]];
  arr1.forEach((arr,i) => 
    res.push(`${arr2[i]}`)
    );
    return res;
}

console.log(merge(arr1,arr2));

Just use merge

$a1=array("red","green");
$a2=array("blue","yellow");
print_r(array_merge($a1,$a2));

Try using the spread syntax.

let recipe = ["dry chapati", "dry chapati", "dry chapati"];
let tags = ["chapati", "less fat", "no oil"];

let result = [...recipe, ...tags];
let result2 = [];
result2.push(...new Set(result));
console.log(result2);

This will give you the result you want.

You question is not clear as what you want to achieve but according to my understanding of the problem. Give below are two possible ways.

 /*If you want to achieve something like
  let c = [{'dry chapati': 'chapati'}, {'dry chapati': 'less fat'}, {'dry chapati': 'no oil'} ]
  */
  let thirdArray = [];
  for (let i = 0; i < recipe.length; i  ) {
    let dish = {
      [recipe[i]]: tags[i],
    };
    thirdArray.push(dish);
  }

  /*If you want to achieve something like
  let c = [{'dry chapati': ['chapati', 'less fat', 'no oil']}. {...}]
  */
  let fourthArray = [];

  for (let i = 0; i < tags.length; i  ) {
    let secondDish = {
      [recipe[i]]: [tags],
    };
    fourthArray.push(secondDish);
  }

You can use LINQ. Zip in jQuery, you can add (https://github.com/multiplex/multiplex.js) LINQ library JS in your script file and try this code.

var arr1 = [1, 2, 3, 4]; var arr2 = ["A", "B", "C", "D"];

var res = arr1.zip(arr2, function(a, b){ return {Num:a, Letter:b} });
